This regulation establishes an exemption from the requirement of a tolerance for residues of cumene sulfonic acid and its ammonium, calcium, magnesium, potassium, sodium and zinc salts when used as an inert ingredient (surfactants, related adjuvants of surfactants) in pesticide formulations applied to growing crops and to animals. Huntsman Petrochemical LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of cumene sulfonic acid and its ammonium, calcium, magnesium, potassium, sodium and zinc salts when applied or used under these conditions.
